      Kang et al noted that “the self-reported varicella history did not accurately predict immunity, especially for individuals who have negative or uncertain varicella history”

      and “serologic screening before vaccination was more cost-effective than universal vaccination.”

      In fact, self-reported history is a simple technique for case inclusion for vaccination. Based on the previous report by Wiwanitkit, in cases where medical personnel reported “a previous infection history,” it is usually reliable.

      Another alternative method that might be cost-effective is asking for self-reported history and then doing further serologic screening in cases with uncertain history or without previous infection history before vaccination should be studied.
